My setup for YouTube on the deck was adding my browser as a non-steam game and letting it open youtube.com/tv in kiosk mode. Worked great for a long time. Today it started giving me a message like “check your device’s app store for the official app” and redirected me to default YouTube.
Anyone else got this problem? Any solutions?

I know it’s not helpful but I don’t have any of these problems. Very much plug and play for me.
